The U1236 is equipped with two independently controlled channels, each featuring its own set of preamp tubes (12AX7) and power tubes (6L6GC).

Its ability to be used for both guitar and bass, adjustable power levels, and built-in equalizer make it an excellent choice for musicians who play multiple instruments or want a single amplifier for both.

If you're looking for a versatile tube amplifier head that can handle both guitar and bass applications, the Univox U1236 is an excellent choice. Its warm and rich tone, adjustable power levels, and built-in equalizer make it a great investment for musicians who value sound quality and versatility.

Details:

Handles pedals really well. Vintage Univox U1236 Guitar and/or Bass Head. 2 6L6 output tubes, 12AU7 tubes and 1 12AX7 tube. Runs at about 35 watts NOT 100 watts .

Fairly recent recap job. All tubes are good. The silver insert in the BASS Eq knob is missing knob there and works fine - SEE PICS. Only the cosmetics of are worn due to its age.

There was something scratched into the face of head that covered up with a magic marker SEE PICS, also, there is split in vinyl handle just vinyl, metal plate inside fine and works just - its only cosmetic SEE PICS. Very good sound. It was designed to work on 117V AC like most vintage amps, so if your from outlet is like 125 volts , you should use a Mauriac. Also, its a good Mod candidate I can include copy of the schematic.
